Abstract:

We consider near-threshold

a_0(980)

-meson production in

\pi N

and

NN

collisions. An effective Lagrangian approach with one-pion exchange is applied to analyze different contributions to the cross section for different isospin channels. The Reggeon exchange mechanism is also evaluated for comparison. The results from

\pi N

reactions are used to calculate the contribution of the

a_0

meson to the cross sections and invariant

K \bar K

mass distributions of the reactions

pp\to pn K^+\bar K^0

and

pp\to pp K^+K^-

. It is found that the experimental observation of

a_0^+

mesons in the reaction

pp\to pn K^+\bar K^0

is much more promising than the observation of

a_0^0

mesons in the reaction

pp\to pp K^+K^-

. Effects of isospin violation in the reactions

pN \to d a_0

,

pd \to \mathrm{^3He/^3H} a_0

, and

dd \to \mathrm{^4He} a_0

, which are induced by

a_0(980)

--

f_0(980)

mixing, are also analyzed.
